Aged about 13 (this would be 1960 or so) I was blown away by this B minor Prelude as played on the organ in the Great Hall of Wyggeston School, Leicester, by a virtuosic – nay, positively Byronic – Richard Armstrong. For many years afterward I dreamed of orchestrating it à la Elgar, but this version suits my talents much better. The bombast of the rock drums added to the synths, half apocalyptic, half Donald Duck, only go curiously to increase the grandeur of this giant of a piece, surely one of Bach's most monumental single movements.
